Designated Russian oligarchs

OLEG DERIPASKA, main owner of En+, co-owner of Rusal and Norilsk Nickel Deripaska, is ranked by Forbes magazine as Russia's 19th-richest businessman with a net worth of $6.7 billion. Deripaska holds regular meetings with Russian President Vladimir Putin, invested heavily in Russia's 2014 Sochi Winter Olympics, and has said his own interests are indivisible from the state's.

En+ has a 48 percent stake in Rusal, one of the world's largest aluminium producers. Rusal is listed in Hong Kong and counts Glencore among its shareholders.

Rusal has assets in Italy, Ireland, Sweden, as well as Nigeria, Guyana, Guinea, and a stake in Australian QAL, the world's top alumina refinery. Over 10 percent of Rusal's total sales go to the United States.

From U.S. Treasury Department: "Oleg Deripaska is being designated ... for having acted or purported to act for or on behalf of, directly or indirectly, a senior official of the Government of the Russian Federation, as well as ... for operating in the energy sector of the Russian Federation economy."

VIKTOR VEKSELBERG, key owner of Renova holding group. Forbes ranks Vekselberg as Russia's ninth-richest businessman with a net worth of $14.4 billion. He is famous for bringing back a collection of Faberge eggs to Russia.

Apart from Russia, Renova has assets in the United States and Europe, of which the most notable are stakes in the Swiss companies Sulzer, Schmolz+Bickenbach and Oerlikon. They are not under sanctions.

Vekselberg and his partners also have a stake in Rusal, which supplies aluminium to the United States and other countries.

After the marriage, he swiftly grew his wealth through investments in Russia's biggest petrochemical company, Sibur.

Forbes says Shamalov is Russia's 72nd-richest businessman with a net worth of $1.4 billion. Shamalov now owns 3.9 percent of Sibur. Gennady Timchenko, a close associate of Putin, holds a stake in the company as well.

Sibur is not under sanctions.

From U.S. Treasury Department: "Kirill Shamalov is being designated for operating in the energy sector of the Russian Federation economy. Shamalov married Putin's daughter Katerina Tikhonova in February 2013 and his fortunes drastically improved following the marriage."

Skoch's father, Vladimir, owns a stake in USM holding. Businessman Alisher Usmanov is a key shareholder in USM. Neither Usmanov nor USM is under sanctions.

Via USM, Skoch's father co-owns Metalloinvest, Russia's largest and the world's second-largest mining company by the size of iron ore reserves, with units in Ireland, Switzerland and Guinea.

USM also has stakes in Megafon, Russia's second-largest mobile operator, in MAIL.RU Group, one of Russia's largest internet companies, and in Russian social networks VKontakte and Odnoklassniki.

Arkady Rotenberg and his brother Boris Rotenberg are already under sanctions due to their close connections to Putin, whom they have known since they practiced judo together in St. Petersburg in Putin's younger days. Arkady Rotenberg is now overseeing the construction of a bridge Putin has championed to Russia-annexed Crimea.

From U.S. Treasury Department: "Igor Rotenberg is being designated for operating in the energy sector of the Russian Federation economy. Rotenberg acquired significant assets from his father, Arkady Rotenberg, after OFAC designated the latter in March 2014.
